For more than a year, the Prius Prime has been the second best-selling plug-in vehicle—surpassed only by the Tesla Model 3. Now the new 2020 version of Prime, due as early as June, will become even more accessible and attractive when its back row expands to accommodate a fifth passenger and adds two USB ports.

It’s been one year since Japan’s Nikkei newspaper reported that Toyota intends to mass-produce an electric car with a driving range of approximately 185 miles. According to multiple reports, Toyota continues to pursue this goal—and to develop an EV with even longer range and able to recharge much faster than today’s electric models. The company has not yet revealed any specific product plans for an electric car in the United States.

Toyota announced today that the design of the Prius Prime will add some excitement when the company introduces a high-performance version of the plug-in hybrid in Japan. While Toyota has not yet confirmed plans to launch GR option packages in the US market, the Prius Prime is the only model in the new performance GR sub-brand that is currently sold in the US. In Japan, the more stylish version of the plug-in hybrid, which offers 25 miles of all-electric range, will be called the Prius PHV GR Sport.

The Toyota Prius Prime plug-in hybrid outsold all other electric models in May. That marked the second straight month in the top spot for Toyota’s plug-in hybrid that grants 25 miles of all-electric driving before resorting to gasoline. The model's relatively low price tag could partly explain why the Prius Prime is beating cars like the Chevy Volt and Tesla Model S, but it’s not the whole story.

The best selling plug-in hybrid so far in 2017 is the Chevrolet Volt, which offers 53 miles of all-electric driving on a charge before reverting to some use of gasoline. But the Toyota Prius Prime—despite only offering 25 miles of all-electric range—is nearly as popular. The two vehicles currently stand as the second and third most popular plug-in electric cars this year.

Japan’s Nikkei newspaper reported today that Toyota intends to mass-produce an electric car with a driving range of approximately 185 miles. According to reports, the automaker will dedicate a team starting next year to develop the vehicle by 2020. The future model will likely use an existing platform—such as Prius or Corolla.

With the introduction of the 2017 Toyota Prius Prime, Toyota’s hesitation with plug-in hybrids appears to be a thing of the past. The Prius Prime plug-in hybrid will offer a EPA-estimated all-electric driving range of up to 25 miles up and at speed up to 84 miles per hour. It's due at dealerships in early November.

Toyota unveiled the new and improved version of its Prius Plug-in Hybrid at the New York auto show on Wednesday. In keeping with the plug-in market’s trend of increasing all-electric range, the new Prius Plug-in Hybrid will double its battery capacity to 8.8 kilowatt-hours—thereby roughly doubling its electric range to about 22 miles.

Toyota announced this week that production of the current generation Prius Plug-in Hybrid will cease in June. “We are hard at work developing the next-generation Prius Plug-in Hybrid,” wrote Nathan Kokes, Toyota brand manager for advanced technology vehicle marketing. “We are looking forward to sharing more details with you as we approach our launch date.”

The ongoing price war between makers of plug-in cars continued this week with the announcement from Toyota that it will cut prices on its Prius Plug-in Hybrid for the 2014 model year. Essentially the same as the 2013 Prius Plug-in Hybrid—and without the garish two-tone paint job recently announced for the Japanese-market 2014 model—the new U.S. market version of the Prius plug-in gains no new visible tech or features, but is more affordable.
